22.22222222222222 is the answer you can simplify it by saying 22.222...
What the hell is that lol
I think for the first one you do 8 times 9 and then 5 times 5 and add them together, I’m not sure though because I learned that a few years ago
the 7 digit is in the ten thousands place
the 0 is in the thousands place
the 6 is in the hundreds place
the 8 is in the tens place
the 1 is in the units place
U/(4^6-2)
would be the answer. Good luck!
